T 0 all whom it may concerns I Be it known that'I, NORMAN J. MooNEY, acitizen of the United States, resldlng at San Francisco, in the countyof San Francisco and Stateof Callfornla, have1nvented certain usefulImprovements in Tobacco- Pipes, of which the following is aspecification, reference being had therein to the accompanying drawing.-r p The invention relates to pipes, and more particularly to the classof tobacco pipes.

The primary object of the invention is the provision of a pipe of thischaracter wherein the bowl and stem thereof are made in separablesections, so that said bowl and stem can bereadily cleaned, and therebyeliminate nicotin frornfilling the channel in the stem and thus chokingthe same, which would impair the draft through the channel when the pipeis in use.

Another object of the invention is the provision of a pipe ofthischaracter wherein the bowl and stem are of novel form, and

the said bowl carries a false bottom, thereby eliminating thepossibility of the burning through of the bowl when thepipe is beingsmoked, and also assuring the cleansing of the pipe with despatch, bothin the bowl thereof and its stem. I t

A further object of the invention is the provision of a pipe of thischaracter wherein the separable parts thereof when assembled, will notonly provide arigid structure, but will have the appearance of anordinary one piece pipe, and the draft through the pipe will not beimpaired through leakage of air between the separable sections of thebowl and stem.

A still further object of the invention is the provision of a pipe ofthis character wherein the mouth piece will prevent the separation ofthe sections of the bowl when said mouth piece is engaged in the stem,and upon the removal of the mouth piece the sections can be readilyseparated for the cleaning of the bowl and stem, and theremoval oi thefalse bottom from the bowl which facilitates the cleaning of the bowland said false bottom, and avoids the charring or burning of the bowlthrough the bottom thereof.

A. still further object of the invention is ing the bowl. 5 i

The open bottom end of the body lO, consembled or disassembled, strong,durable,

and inexpensive in manufacture.

With these and other objects in view, the invention willjbe more fullydescribed, il1ustrated in the accompanying drawing, and speclficallypointed outin theclaims which are attached hereto, and form a partofthis 7 application.

sectional Fig. 5 is a bottom plan view of the bowl and stem with theseparable section removed.- 1

Fig. 6 is a plan View or the separable section. I 1

Similar reference characters indieatecorresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the toibacco pipe comprises a body,1 0, which con-- stitutes the bowl proper and has formed therewith aportion 11 ofthe stem, the other portion 12 of which is integral with aseparable bottom 13 for the body 10, constitutstituting the bowl and theportion 1101: the stem, is formed with a dove tail shaped groove 14,which extends longitudinally of said stem, while formed on the portion12 and the bottom 13 is a dovetail shaped rib 15, corresponding to thegroove 14, to be detachably received therein, and in this manner thebottom 13 and portion 12 are detachably locked with the body 10 to theportion 11 and this is efi'ected on the sliding of the rib 15 into thegroove 14;, through either end thereof.

The portions 11 and 12 of the stem are channeled at 16 to provide thedraft passagelongitudinally through the stem, which communicates withthe body'10 interiorly' thereof. V

The passage at the outer free end of the stem is enlarged and formedwith internal threads 17 for detachably receiving a threaded nipple 18,which is slightly larger than:

the enlarged threaded portion of the passage, so as to spread theportions 11 and 12 on the engagement of the nipple 18 in the enlargedportion of the passage to firmly clamp'thereon a ring or sleeve 19,which is telescoped upon thev free end of the stem,

Removably ntted in the open end of the body 10 is a false bottom 22,which is of substantiallyqcup shape, and this bottom is received in aseat 23 therefor, provided interio'rly vin the body 10, the bottom 22 inits periphery being provided with a lug 24:, which is received in anotch 25 in the wall of the seat 28, so as to prevent rotation of thefalse bottom when held within the seat, and also to assure theregistration of the opening 26 in said false bottom 22 with the passagein the stem, so that direct draft will be had through the stem andmouthpiece from the body 10 of the pipe.

On the removal of the mouth piece from the stem of the pipe, the bottom13 and the portion 12 can be separated from the body and portion 11,which portions 11 and 12 'constitute the stem, and thus the false bottom22 can be removed from the body 10, so that both the body and'the stemcan be readily cleaned with despatch, and likewise the false bottomcleaned.

The pipe, with the separable parts, can be readily assembled anddisassembled in a convenient manner. a

on the engagement of the nipple 18 in the free end of the stem, thesleeve 19 will bind upon the portions 11 and 12, as said-portions I areslightly spread, and in this manner the separable sections of the bodyand stem will passage in the stem be firmly locked together withoutpossibility of the leakage of air from the draft passage on the smokingof the pipe, nor will there be any possibility of the separation of theparts of the pipe while in use, and in the act of smoking the same.

From the foregoing, it is thought that the construction and manner ofassembling and disassembling of the parts of the pipe will be clearlyunderstood, and therefore, a more extended explanation has been omitted.

lVhat is claimed is 1. A device of the character described ineluding abody forming the walls of a bowl and provided with a seat at its lowerend and also having a stem portion leading there from, a bottom for thebody having a stem portion leading therefrom,means for securing the bodyand its stem and the bottom and its stem in detachable engagement, and afalse bottom positioned entirely within the body and removably -heldagainst the seat and supported by the bottom.

2. A device of the character described including a body forming thewalls of a bowl and provided at its lower open end with a seat andhaving a stem portion leading therefrom, a bottom for the body having astem portion leading therefrom, the stem portions being provided with asmoke passage, the bottom and its stem portion being provided with agroove, a rib formed on the bottom and its stem portion for detachableinterlocking engagement with the groove,

a false bottom for the body removably held against the seat andsupported by the bottom and further provided with an opening forregistration with the smoke passage in the stem portions, andcooperative means formed on the false bottom and in the seat forpreventingrotary movement of the false bottom.,

.In' testimony whereof. I affix my signaturc.
